Xfinity Stream App on Roku Streaming Issue

Within the last few weeks or so I've been experiencing an issue with all of my Roku devices with the Xfinity Stream application.  What I have found is that if I'm streaming a Cloud DVR recorded show, sometimes while watching the show I lose all other remote functionality such as rewind, fast forward, pause, etc.  I'm forced to either wait until the show has ended (watching of course all of the commercials), or I have to find other ways to jump out of the application and start all over again with the recorded show.

I have tried the following so far:

1.  Rebooting the Roku.

2.  Uninstalling the Xfinity Stream application, and reinstalling it.

3.  Trying other Roku streaming devices (I have three), but all of them are having the exact same issue.

4.  Resetting my internet connection.

So far nothing has seemed to help.  Up until a few weeks ago the streaming app always worked perfectly on my devices.  I'm wondering if there was an update which may have triggered this.

Thanks much.  Hopefully someone has an idea of what is going on, or someone at Xfinity reads this and can find a solution.
